They’re at DEFCON 1 on “American Idol.” The Armageddon will be televised.

Things are going really, really well between “Idol” judges Mariah Carey and Nicki Minaj. And by really, really well, we mean that neither has pulled out a gun and shot the other. But stay tuned.

Apparently during Tuesday auditions in Charlotte, N.C., Minaj de-railed the process by swearing at Carey and threatening, “I’m gonna knock you out,” with Carey firing right back.

In footage obtained by TMZ, Minaj is clearly furious, shouting “I told them I’m not (expletive) putting up with her (expletive) highness over there.”

Carey can be heard saying, “Oh why, WHYYYY do I have a 3-year-old sitting around me?” I can’t see my kids, because you decided to act like a little crazy (expletive) and go all around the stage.”

Sources say Nicki later threatened to “knock out” Carey before the video starts.

In related news, FOX has decided to turn “American Idol” into a pay-per-view event.

The fracas erupted Carey and Minaj were sitting at the judge’s table, with Keith Urban sitting between them and Randy Jackson sitting on the far end, next to Carey.

The issue was allegedly a contestant’s performance.

TMZ provided a blow-by-blow account:

Minaj: “Get this (expletive) in self control. Get in control. Get in control.”

Jackson: “Settle down, settle down.”

Minaj: “Don’t lose your head. Don’t lose your head (inaudible). Don’t tell me I’m a gangster (inaudible) every 5 minutes. So every time you patronize me, I’m-ma take it back, and if you’ve got a (expletive) problem, handle it. “I told them I’m not (expletive) putting up with her (expletive) highness over there. Figure it the (expletive) out. Figure it out.”

Carey: “Oh why, WHYYYY do I have a 3-year-old sitting around me?”

Minaj: “I’m not gonna sit here every (expletive) minute to have you come down and harass me every minute everyday.”

Carey: “I can’t see my kids, because you decided to act like a little crazy (expletive) and go all around the stage.”

According to MouthToEars.com, producers ended the auditions for the day so the two judges could cool down, which TMZ confirmed.

In a video clip recorded by a student, a psychology instructor at Orange Coast College told her class that the election of Donald Trump was “an act of terrorism” – prompting an official complaint from the school’s Republican Club.
